WEB-ROLL STAND.

Application led November 29, 1920. Serial No. 427,161.

' To all lwhom t may concern.

Be it known that I, ALLAN J. CLINE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Web-Roll Stands, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to stands or reels for supporting a plurality of rolls of web so that they can be conveniently supplied to a printing press or other machine through which the web is to be conducted for further operations. In feeding webs to printing presses particularly, it is necessary at times to adjust the roll longitudinally of itself, or transversel to the path of the web, as it is unreele to secure the proper marginal alinement. Heretofore, where roll stands and a plurality of rolls have been em loyed the roll supports have been mounte on a rotary shaft journaled in bearings carried by standards, and the desired marginal ad- 25 justment has been obtained by making one of the standards adjustable in such manner that by moving it laterally the shaft with the roll supports carried by it would be adjusted endwise. This construction, however, is unsatisfactory, and the object of my invention is to provide improved means for attaining the same end. I accomplish my object as illustrated in the drawings and hereinafter described. What I regard as 'new is set forth in the claims.

In the accompanying drawings,-

Fig. 1 is an end view of a roll stand embodymg my improvements, some parts being broken away; and

Fig. 2 is a partial sectional view showing the details of my improved construction.

As shown in the drawings, my improved stand comprises a roll support carrying shaft 3, one end of which is mounted in an 45 ordinary bearing carried by a standard which is not shown, as it may be an ordinary fixed standard of any suitable description, and the bearing may be of any approved construction which will permit endwise ever, shown in my application of even date herewith for improvements in paper roll chucks. The opposite end of the shaft 3 is mounted in a suitable bearing 4 carried by a standard 5, as shown in detail in Fig. 2. The shaft is not mounted directly in said bearing, but is fitted into the hub 6 of a wormv wheel 7 in such manner that it may move longitudinally therein, but rotates therewith. This is best accomplished by a key 8 interposed between .the hub 6 and the shaft 3, as shown in said figure. The hub 6 has no longitudinal movement in the bearing 4, but on the contrary is held against such movement b an annular plate 9 which is secured to til screws 10, and overlaps the margin of the bearing 4, as shown. By this construction the shaft 3 is free to move endwise through the hub 6. v

y The worm wheel 7 is provided for the purpose of rotating the shaft 3 to move one or another of the rolls carried by it into posi-v tion for use, such rolls being mounted between a pair of roll supports 11 having spindles or chucks 12 which engage the oppositel ends of the usual mandrel which forms the core of a roll. Usually the roll supports 11 are equipped to carry three rolls arranged equally distant apart so that by rotating the shaft- 3 any one of the rolls can be moved into or out of operative posi,- tion. The worm wheel 7 is arranged t0 be rotated by a motor 13 mounted on a bracket 14 carried by the standard 5, as shown in the drawings. This motor is operatively connected with the worm wheel 7 by a pin'- ion 15 mounted on the armature shaft 16 of the motor and meshing with a gear 17 mounted on a countershaft 18 which carries a worm 19 in mesh with the worm wheel 7, as shown in Fig. 1. Suitable bearings 20, 21 for the countershaft 18 are provided on the standard 5, asV indicated by dotted lines-in bviously it is necessaiiy'A that the shaft 3 be held firmly against endwise movement exe outer end of the hub 6 byy cept when it is to' be adjusted longitudinally, and the devices for so holding it and also for moving it endwise will now be described. As shown in Fig. 2, a housin 22 1s provided which is secured to the stan( ard 5 over the outer end of the bearing 4. and is provided with a bearing 23 in which is journaled the hub 24 of a worm wheel 25. This worm wheelis coaxial with the shaft 3, and its hub 24 is providedl with a radial flange 26 forming a groove to receive the bearing 23 and prevent endwise movement of said worm wheel.

The hub 24 is internally screw-threaded and in it is fitted a screw 27 provided with a head- 28 which abuts against the outer end of the shaft 3 and is connected therewith by a flanged ring 29 secured by screws 30. By this construction the shaft 3 is free to yturn independently of the screw 27, but endwise movement of said screw correspondingly moves said shaft. The screw 27 is held against rotation by means of a cap 31 which is secured to the outer end of the housing 22 by screws 32, and is provided with a key 33 fitted in a keyway in the outer end of the screw, as shown in Fig. 2. By this construction, by rotating the worm wheel 25 the screw 27 will be caused to move endwise in one direction or the other, which motion will bel communicated to the shaft 3, as above described, thereby similarly adjusting the roll supports carried by it, and conse'quently adjusting the margins of the web laterally. The worm Wheel 25 is rotated by means of a worm 34 mounted on the armature shaft 35 of a reversible electric motor 36 supported by the standard 5, as best shown in F ig. 1. By this construction, whenever the operator wishes to adjust the margins of the rolls all he needs to do is to start the motoi` 36 in the proper direction,

whereupon the shaft 3 will be moved end.

wise slowly, carrying the rolls with it. Instead of using a reversible motorvv any suitable reversing mechanism may be interposed between the motor and the worm. One end of the armature shaft 35 is preferably squared as shown in Fig. 1 so that in case of an emergency the worm may be rotated by the a plication of a crankA thereto.
